should be easy. however the boat is nearly 21 feet long. go with a 5.7 if you are sticking to Gen 1 SBC motor over the 5.0

@Scott06 did a similar swap with his boat.
Scott, sorry I haven't responded since I made the initial post; I'm a train conductor and don't get much time off. I already have a Mercruiser 5.0L sitting in my garage. The motor has less than 80 hours on it, and it runs great. Every month or so I pull it out of the garage and run it for a couple of minutes. So instead of trying to sell it, I would like to swap it out. I am looking around on the internet trying to gather information on this.
